To all whom it may concern:

Be it known that I, FRIEDRICH BALAssA, of Budapest, AustriaI-Iungary, asubject of and whose post-oflice address is Rezso tr No. 1, Budapest, X,Kingdom of Hungary, Austria-Hungary, have invented a new and usefulImproved Starting Device for Internal-Combustion Engines, of which thefollowing is a specification.

I This invention relates to starting devices for internal combustionengines.

The object of the present invention is to provide means for startinginternal combustion engines with ease and certainty with the assistanceof a single workman.

In the accompanying drawings, Figures 1 and 2 show, by way of example,the improved starting device applied to a motor vehicle or portableengine; Figs. 3 and 4 show the device in two positions on a largerscale, and Figs. 5 and 6 are detail views hereinafter described.

In carrying out the invention a toothed gear a is provided on a shaft arotatably supported in the frame of the engine. Pivoted on the shaft ofis a forked lever e in which is journaled the shaft 0 of a gear aengaging with the gear a. Secured to the shaft 0 of the gear a is asleeve or pulley d which is covered with, or is made of vulcanite, wood,leather, india-rubber or any other suitable material and which can bepressed against the rim of the fly-wheel of the engine by rotating theforked lever 6 around the shaft a On the frame of the engine-is'provideda bracket j. A lever is shown in end elevation in Fig. 5 and in sideelevation in Fig. 6 has a projecting pin 70 which engages in ahorizontal slot j in the bracket j and a pin 70 which passes through anorifice in the lever e. Loosely mounted on said pin 70 is a hand lever fhaving a pin f which passes through a concentric slot in the lever c andis adapted to engage with the side of the lever is.

k is a rod mounted to slide in the bracket j and having its end inproximity to a lug h'which is mounted on the cam shaft of the engine.

In order to start the engine the workman pumps or sprays with a smallstarting pump m a portion of fuel into the explosion chamber and thenlifts the hand lever f into the position shown in Fig. 3. The rotationof said lever on its pivot 70 causes the pin f to engage with the sideof the lever is and force it to the right so that the pin 10 moves tothe right hand end of the horizontal slot 7' this causes the pin is? tomove downward a little and rotates the lever e on its pivot a so as topress the pulley cl against the rim of the flywheel g. The crank b isthen rotated by the workman whereupon through the gears a and a and thepulley cl which engages frictionally with the flywheel g' the latter isset in motion. The movement is continued until the piston reaches theinner dead'point. At this moment the fuel previously sprayed through thestarting pump m and finely diffused as a result of the compression inthe cylinder of the engine is ignited by a spark due to the magneto andthe first explosion follows. At the same time, that is to say at thesame moment that the spark occurs, the rod k is pressed downward by thelug and engaging with the side of the pin 76 causes it to move in theslot y' tion that as soon as the engine causes an accelerated movementof the flywheel due to the first explosion the pulley d is automaticallydisengaged from the rim so that no movement will be transmitted backthrough the gears a a to the handle 5 and any possibility of a shock orar to the workman is avoided.

The device can readily be applied to any existing stationary or portableengine if desired.

What I do claim as my invention, and de sire to secure by Letters Patentof the United States, is

1. The combination with an internal combustion engine having a flywheel,of a pulley, a hand crank and gearing for rotating said pulley, manuallyoperated means for forcing said pulley into frictional engagement withthe flywheel, and means for autov the end of said lever, apin on saidcrank en- 7 matically disengaging said pulley and flywheel at the momentwhen the first explosion occurs.

2. The combination with anvinternalcom-i bustion engine having aflywheel, of a pulley, a hand crank and gearing for rotating saidpulley, a lever on which said pulley is mounted journaled co-axiallywith the hand crank, manually operated means for'rotating said lever soas to force the pulley into frictional engagement with the flywheel,

and means for automatically disengaging said pulley and flywheel at themoment when the first explosion occurs.

3. The combination with an'internal combustion engine having a flywheel,of a rotatable pulley mounted on a lever pivoted to the frame of theengine, a crank pivoted at gaging-in a slot in a fixed part of theengine, manuallyoperated means for moving said pin in said slot torotate the lever on its pivot and force said pulley intoengage ment withthe flywheel, and means operating automatically when the first explosionoccurs to move said pin in the opposite div rection soas to withdraw thepulleyfrom 4. The combinatlon with an'internal combustion 'englne havinga v flywheel, of a Copies of this patent may be obtained for 5. Thecombination with an internal corn-V bustion'enginehaving a flywheel, ofashaft journaled inthe engine frame, a lever pivoted on said shaft, apulley rotatably mounted on said lever, va hand lever" pivoted on saidlever,a pin on said hand lever proj ecting through a slot on said lever,a crank also pivoted on said'l'ever co-aXially with said hand lever andadapt'edto be engaged f by the pin 'on said handlevena pin on said crankadapted to move'ina slot in the frame, a rod slidably supported on saidframe adapted to engage. with the pin on said crank and a lug on the camshaft of the en- 7 7 inc for o eratin said rod when i ition occurs. a aIn testlmony whereof I have hereunto set my hand 1n presence of twosubscribing w1tnesses; l
